Mixing Methods in Psychology [PDF ebook] 
The Integration of Qualitative and Quantitative Methods in Theory and Practice

Can qualitative and quantitative methods be combined effectively in psychology? What are the practical and theoretical issues involved? Should different criteria be used to judge qualitative and quantitative research?The acceptance of qualitative research methods in psychology has lead to a split between qualitative and quantitative methods and has raised questions about how best to assess the validity of research practice. While the two approaches have traditionally been seen as competing paradigms, more recently, researchers have begun to argue that the divide is artificial.Mixing Methods in Psychology looks in detail at the problems involved in attempting to reconcile qualitative and quantitative methods both within and across subjects. All angles of the debate are discussed, covering areas asdiverse as health, education, social, clinical and economic psychology. The contributors, who are some of the leading figures in the field, present theoretical and methodological guidance as well as practical examples of how quantitative and qualitative methods can be fruitfully combined. By aiming to bridge the gap between the two methods, this book reveals how each can inform the other to produce more accurate theories and models of human behaviour.This groundbreaking text will be essential reading for students and researchers wishing to combine methods, or for anyone who simply wants to get a better understanding of the debate.
